What happens when I press the spacebar on my Microsoft SwiftKey Keyboard?

Within your Microsoft SwiftKey Keyboard, there are three available options with regards to how the spacebar functions.

(No autocorrect selected) Spacebar will always insert a space – This means that pressing the spacebar will not affect your predictions or what you are typing. It will simply function as a spacebar. Your words will not be corrected or completed unless you tap the prediction buttons.

(Autocorrect selected) Spacebar will complete the current word– Selecting this option means that pressing spacebar when typing a word will automatically enter the middle prediction. If you are not currently typing, then spacebar will simply enter a space, or a period if a space is already present (uncheck 'Quick period' to disable this).

(Auto insert prediction selected) Spacebar will always insert a prediction – Selecting this option means that pressing spacebar always enters the middle word prediction (plus one space), including next words. The option will never enter a space alone.
